A Novel, Improved Pulse for Digital Communication, Recording and Storage Systems
Description
Currently, modem and digital transmission systems use the raised-cosine ""Nyquist"" pulse shape for conveying data electronically. A new pulse shape has been developed at the University of Alberta that has less inter-symbol interference and a smaller average probability of error than the current standard. The new electrical pulse has smaller maximum distortion, a more open receiver eye, and a smaller probability of error in the presence of symbol timing error than the Nyquist raised-cosine pulse for the same excess bandwidth.
For additional information see US Patent Application US20030185313
Advantages
This technology offers: - A more open receiver recovered signal eye.
- Less intersymbol interference than current pulse shapes.
- Less co-channel interference than current pulse shapes.
- Superior error rate preformance.
- More resistant to timing jitter.
Potential Markets
- This pulse would be beneficial to manufacturers of modems, cell phones and other digital communication devices.
- Useful for digital recording and storage systems.
